Amps usually receive their signal through RCA wires. Your radio should have one pair of RCA outputs on the back. (red and white) You will adjust your subwoofer volume by adjusting the gains on the amplifer (little knob next to the RCA inputs of the amp), then you can turn up the bass on your radio.

If your indash radio does not have RCA outputs, you can do two things. You can purchase a line level converter and hook it to one of the rear speakers. This will allow you to tap into the speaker wire, then convert the signal to RCA. Then you plug your RCA cables in there. The other (my recommendation) is to purchase an "add an amp" wiring harness. This harness will install between your radio and vehicle harnesses. It will have RCA output and remote wire. Then you run those back to your amp and there you go. You can find these at the scosche or PAC websites. You can also try www.crutchfield.com

Your unit should have 2 plugs in the back...one for the audio and power wires to connect to your factory connections and the other plug is just RCA connections for your video, subs and front speakers. If you have a 4 channel amp and a amp for your subs, you will have to split the 4 channel amp down to 2 and run them to your front RCA connections. Subs will connect to the sub connections. If yours are not listed then you may have to track down a wiring diagram. Hope this helps.

Use process of elimination. Connect the speakers that are hooked up to your amp directly to the radio, if they work check your amp. Make sure the rca jacks are connected properly. Sometimes the radio has rca's that are "inputs", make sure they're connected to the "output" rca's. If those are ok, your amp may be faulty. Try the amp on your friend's car see if it works. If it doues your radio might be at fault...or just bad rca cables. like i said, use process of elimination to narrow down the faulty equipment.

We'll start with powering the system up. YOu will need to run your power wire from the battery. It must have a fuse just after the battery. Run the negative to the chassis of the vehicle. On the back of the radio, there will be a blue wire labeled remote/antenna. This wire needs to be connected to the amp. This is what turns it on and off when you power up the radio. Next you will need to run the RCA cables from the back of the radio to the amp. Now you are ready to hook up the sub woofers to the output side of the amp.

Check your rca cables they might be loose or not connected to the amp or the radio. Sometimes those rca cable outlets get worn out by being bumped, moved, hooking up and pulling out connectors. Plug in your rca cords and wiggle them on the amp while radio is on and see if the music cuts in and out

connect speaker wiring for car to speaker wire side. plug the rca's into the amp ground the ground wire. run a live from the battery to the power on the crossover and run the remote wire to the blue (iso connector) wire coming from the back of the radio

You can not connect the speaker lines directly to the RCA inputs of your amplifier. But you can connect them to your amplifier if your amp has a high level input. Most of the time it looks just like the speaker jacks of the amp, but smaller. It will be labeled high level input or speaker input. Sometimes an amplifier will have a jack for a wiring harness just for this purpose. Some amplifiers have them and some don't.

If your amplifier does not have them, you can purchase a line level adapter at most anyplace that installs car stereos. it converts the speaker level to the proper level of the RCA input.Just follow the instructions on how to connect it.

If you try to connect the speaker outputs directly to the RCA input of the amplifier you will blow up the pre-amp in your amplifier.

I hope this was helpful to you, if so a good rating is always appreciated.
